Grocer::Server can send feedback

I was just trying to test for feedback in light of issues such as #14. This issue labelled as enhancement seems to suggest that this should be possible. Here’s the rspec test snippet I came up with for this. I threw in the second expectation after I found #80 just to be sure.

require 'spec_helper'

describe 'grocer push notifications' do
  before(:each) do
    @server = Grocer.server(port: 2195)
    @server.accept # starts listening in background
  end

  after(:each) do
    @server.close
  end
  let(:notification) do
    Grocer::Notification.new(
      device_token:      "wrongtoken",
      alert:             "I should trigger feedback.",
      badge:             42
    )
  end
  let(:cert) { "#{Rails.root}/app/assets/push_notifications/apple_push_notification_dev.pem" }
  let!(:push_client) { Grocer.pusher(certificate: cert) }
  let!(:feedback_client) { Grocer.feedback(certificate: cert, retries: 3) }

  it 'should have feedback for an invalid notification' do
    push_client.push(notification)
    expect(feedback_client.count).not_to eq(0)
  end

  it 'should have feedback for an invalid notification with to_a fix' do
    push_client.push(notification)
    expect(feedback_client.to_a.count).not_to eq(0)
  end
end
